Newton CDM Fibran XPS-500C for Basement Waterproofing Systems - Closed-cell Slotted Insulation Board

CDM Fibran XPS-500C boards are used to form a 50 mm insulated spacer adjacent to the Basedrain and Floordrain drainage channels within the cavity drain waterproofing system, where it remains dimensionally stable even when fully immersed.

The insulation boards have a heat-hardened surface to increase point load capability below-studded membranes and feature specifically designed slots to the underside of the boards, that in combination with the perimeter and spine drainage channels of cavity drain waterproofing form a fully drained supporting spacer below the floor drainage membrane.

The insulation boards can also be used as a protection for liquid waterproofing membranes applied externally to new earth-retained structures or retained walls, providing protection, insulation and drainage within one product.

Features and benefits:

• Third-party tested to confirm the load capability for use below Newton studded, cavity drain membranes.
• Excellent thermal insulation characteristics, with a very low coefficient of thermal conductivity.
• Closed cell structure with no connecting capillaries resulting in high resistance to water absorption and diffusion of water vapour.
• Capable of permanent submersion in water.
• Fully inert when subjected to climatic variations.
• High mechanical and compressive strength and high dimensional stability.
• Does not contain CFCs, HCFCs, PBDEs, PFOA or PFCs.
• Easy to transport, cut and apply.
• 100% recyclable.
• Completely rot-proof and does not develop any mould or other efflorescence.
• No nutritional value for rodents, insects, etc.
• Good resistance to acids, alkalines, aggressive ground containments and inorganic gases.
• Suitable substrates include compacted, clean, level surfaces, basement concrete floor slabs and rafts, earth-retained walls of concrete, mortar or insulating concrete forms (ICF) and compacted blinding.
• CE marked.
• Life expectancy is equivalent to the building in which it is installed (estimated at 50 years).
